Visualizing Aggregate Squeeze

For the IDM (Improved Decision Making) project, one of the problems of collecting squeeze data is displaying it with the following constraints:
1) The teacher may not want to be at the computer to know the current squeeze-interest
2) It may not be appropriate to display each individual users squeeze, but it would be good to get more than a one-dimensional value for the aggregate squeeze interest.

Above is an exhibit from the SF MOMA that uses a fan, fabric and weights to create a dynamic display. Using a similar system, but with multiple fans, we might be able to display more than one-dimensional squeeze information without losing any privacy.

On the other hand, it might be really confusing :)
